Abstract
BACKGROUND Laparoscopic surgery (LS) is hypothesized to result in milder proinflammatory reactions due to less severe operative trauma, which may contribute to the observed clinical benefits after LS. However, previous systematic reviews and meta-analyses on the impact of LS on immunocompetence are outdated, limited and heterogeneous. Therefore, the humoral response after laparoscopic and open colorectal cancer (CRC) resections was evaluated in a comprehensive systematic review and meta-analysis. METHODS Included were randomized controlled trials (RCTs) measuring parameters of humoral immunity after LS compared to open surgery (OS) in adult patients with CRC of any stage. MEDLINE, Embase, Web of Science (SCI-EXPANDED), Cochrane Library, Google Scholar, ClinicalTrials.gov and ICTRP (World Health Organization) were systematically searched. Risk of bias (RoB) was assessed using the Cochrane RoB2 tool. Weighted inverse variance meta-analysis of mean differences was performed for C-reactive protein (CRP), interleukin (IL)-6, IL-8, tumour necrosis factor (TNF)α and vascular endothelial growth factor (VEGF) using the random-effects method. Methods were prospectively registered in PROSPERO (CRD42021264324). RESULTS Twenty RCTs with 1131 participants were included. Narrative synthesis and meta-analysis up to 8 days after surgery was performed. Quantitative synthesis found concentrations to be significantly lower after LS at 0-2 h after surgery (IL-8), at 3-9 h (CRP, IL-6, IL-8, TNFα) and at postoperative day 1 (CRP, IL-6, IL-8, VEGF). At 3-9 h, IL-6 was notably lower in the LS group by 86.71 pg/ml (mean difference [MD] - 86.71 pg/ml [- 125.05, - 48.37], p < 0.00001). Combined narratively, 13 studies reported significantly lower concentrations of considered parameters in LS patients, whereas only one study reported lower inflammatory markers (for CRP and IL-6) after OS. CONCLUSION The increase in postoperative concentrations of several proinflammatory parameters was significantly less pronounced after LS than after OS in this meta-analysis. Overall, the summarized evidence reinforces the view of a lower induction of inflammation due to LS.

Abstract
PURPOSE Surgical removal of the cancerous tissue remains the cornerstone of curative treatment for colorectal cancer and results in an inflammatory response. An exaggerated inflammatory response has been implicated in the promotion of tumor proliferation and has shown associations with postoperative complications. Literature on the preferred surgical technique to minimize inflammatory response is inconclusive. Therefore, the aim of this study was to assess the inflammatory response and postoperative incidence of infectious complications following surgery for colorectal cancer. METHODS Embase, PubMed, and Cochrane databases were searched for RCTs that reported inflammatory parameters as a function of surgical modality only. Data related to CRP or IL-6 levels on postoperative days 1 and 3 and data related to postoperative infections were subject to a pairwise meta-analysis to compare open versus laparoscopic techniques. RESULTS The literature search and screening process yielded 4151 studies. Ten studies met criteria, including 568 patients. Only studies on laparoscopic and open surgery were found. Pooled analyses found lower Il-6 and CRP levels on postoperative day 1 and lower CRP levels on postoperative day 3 for laparoscopic surgery compared to open surgery. However, there was no difference in incidence of postoperative infectious complications. CONCLUSION The findings of this study indicate a superior inflammatory profile for laparoscopic surgery compared to an open approach for colorectal cancer surgery. For future research, it would be worthwhile to conduct a randomized controlled trial to compare the postoperative inflammatory response and related clinical outcomes between minimally invasive surgical approaches, including laparoscopic and robot-assisted surgery.

Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide. The main treatment options are laparoscopic (LS) and open surgery (OS), which might differ in their impact on the cellular immunity so indispensable for anti-infectious and antitumor defense. MEDLINE, Embase, Web of Science (SCI-EXPANDED), the Cochrane Library, Google Scholar, ClinicalTrials.gov, and ICTRP (WHO) were systematically searched for randomized controlled trials (RCTs) comparing cellular immunity in CRC patients of any stage between minimally invasive and open surgical resections. A random effects-weighted inverse variance meta-analysis was performed for cell counts of natural killer (NK) cells, white blood cells (WBCs), lymphocytes, CD4+ T cells, and the CD4+/CD8+ ratio. The RoB2 tool was used to assess the risk of bias. The meta-analysis was prospectively registered in PROSPERO (CRD42021264324). A total of 14 trials including 974 participants were assessed. The LS groups showed more favorable outcomes in eight trials, with lower inflammation and less immunosuppression as indicated by higher innate and adaptive cell counts, higher NK cell activity, and higher HLA-DR expression rates compared to OS, with only one study reporting lower WBCs after OS. The meta-analysis yielded significantly higher NK cell counts at postoperative day (POD)4 (weighted mean difference (WMD) 30.80 cells/µL [19.68; 41.92], p < 0.00001) and POD6-8 (WMD 45.08 cells/µL [35.95; 54.21], p < 0.00001). Although further research is required, LS is possibly associated with less suppression of cellular immunity and lower inflammation, indicating better preservation of cellular immunity.

Abstract
For patients with colorectal cancer, minimally invasive surgical methods, particularly laparoscopic methods, are now the preferred course of therapy. This research is performed to investigate the effects of laparoscopic radical resection on patients with colorectal cancer. A total of 100 colorectal cancer patients treated in our hospital from January 2017 to January 2019 were enrolled. The subjects were divided into observation (n = 50) and control (n = 50) groups and treated with laparoscopic surgery and laparotomy, respectively. As well as postoperative complications and survival rates, the levels of inflammatory substances, stress response, immunological function, and perioperative markers were compared between the two groups. There was no significant difference in the postoperative exhaust time between the two groups (P > 0.05). Compared with the control group, the observation group showed longer operation time, faster recovery of intestinal function, shorter hospital stay, and less intraoperative bleeding amount (P < 0.05). The serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol at 1 d, 3 d, and 5 d after surgery were significantly higher than before in both groups (P < 0.05). Moreover, the serum contents of hs-CRP, TNF-α, IL-6, norepinephrine, adrenaline, and cortisol in the observation group were significantly lower than that in the control group (P < 0.05). At 10 days following surgery, immune index levels had dramatically increased in both groups, with noticeably higher immune index levels in the observation group than in the control group (P < 0.05). There were no appreciable differences in the two groups' 2-year survival rates (P > 0.05), but the complication rate was much greater in the control group (P < 0.05). To sum up, after laparoscopic surgery, patients had fewer complications, shorter hospital stay, lower inflammatory factor expression, less stress response, better immune function, less trauma, faster recovery, and improved quality of life.

Abstract
BACKGROUND The effectiveness of transversus abdominis plane block (TAP) on pain management after laparoscopic colorectal surgery (CRS) remains unclear since the only relevant meta-analysis on this topic did not separate laparoscopic CRS from open CRS. The aim of the study was to compare the analgesic efficacy and safety of TAP with non-TAP in patients undergoing laparoscopic CRS. METHODS Four databases were searched for randomized controlled trials (RCTs) on this topic using relevant keywords. Two authors independently completed evidence selection, data extraction, and critical appraisal. Available data were pooled in the random-effects model, and point estimates with 95% confidence interval (CI) were reported for postoperative pain at rest and on coughing, opioid consumption, length of hospital stay, and adverse events. RESULTS A total of 14 RCTs (n = 1216) contributed to the present synthesis. Pooled result showed that patients in the TAP group had lower pain at rest than those in the non-TAP group at postoperative 2-h (mean difference [MD] = -1.42; P < 0.05), 4-h (MD = -0.97; P < 0.05), 12-h (MD = -0.75; P < 0.05), and 24-h (MD = -0.61; P < 0.05). Patients in the TAP group also had lower postoperative pain on coughing than those in the non-TAP group on the first day (MD = -1.02; P < 0.05). Moreover, TAP had lesser postoperative opioid consumption than non-TAP (standardized mean difference, -0.26; P < 0.05; I-square = 20%), and there were non-significant differences in hospital stay and adverse event between the two groups. CONCLUSION Intraoperative TAP is a safe and feasible pain management for laparoscopic CRS, particularly it is recommended when patient-controlled analgesia is not delivered. Therefore, laparoscopic TAP block might be a favorable administered strategy.

Abstract
BACKGROUND The purpose of this study was to compare the clinical efficacy of robotic right colectomy (RRC) and laparoscopic right colectomy (LRC) in the treatment of right colon tumor. METHODS We systematically searched PubMed, Web of science, EMBASE ClinicalTrials.gov and Cochrane Central Register for studies (studies published between January 2011 and June 2020). The included studies compared the clinical efficacy of RRC and LRC in the treatment of right colon tumor, and analyzed the perioperative data. RESULTS Our meta-analysis included 10 studies involving 1180 patients who underwent 2 surgical procedures, RRC and LRC. This study showed that compared with LRC, there was no significant difference in first flatus passage (weighted mean difference [WMD]: -0.37, 95% CI: -1.09-0.36, P = .32), hospital length of stay (WMD: -0.23, 95% CI: -0.73-0.28, P = .32), reoperation (OR: 1.66, 95% CI: 0.67-4.10, P = .27), complication (OR: 0.83, 95% CI: 0.60-1.14, P = .25), mortality (OR: 0.45, 95% CI: 0.02-11.22, P = .63), wound infection (OR: 0.65, 95% CI: 0.34-1.25, P = .20), and anastomotic leak (OR: 0.73, 95% CI: 0.33-1.63, P = .44). This study showed that compared with LRC, the lymph nodes retrieved (WMD: 1.47, 95% CI: -0.00-2.94, P = .05) of RRC were similar, with slight advantages, and resulted in longer operative time (WMD: 65.20, 95% CI: 53.40-77.01, P < .00001), less estimated blood loss (WMD: -13.43, 95% CI: -20.65-6.21, P = .0003), and less conversion to open surgery (OR: 0.30, 95% CI: 0.17-0.54, P < .0001). CONCLUSIONS RRC is equivalent to LRC with respect to first flatus passage, hospital length of stay, reoperation, complication, and results in less conversion to LRC.

Abstract
OBJECTIVE To investigate the action mechanisms of electroacupuncture (EA) on postoperative immunosuppression. METHODS Male C57BL/6 mice (5`-7 weeks old) were randomly divided into: the sham injury group, the surgical trauma stressed group, the EA group [surgery + 2/100 Hz EA at Neiguan (PC 6)], and the EA+ Nal (surgery + EA + intraperitoneal injection of naloxone). Abdominal surgical trauma stress mice model was established. EA was performed on bilateral PC 6 acupoints by an EA apparatus (2/100 Hz) for 20 min once a day for 3 days. The mRNA expressions of MOR, DOR, and KOR in thymus and L3`-L5 dorsal root ganglions (DRG) were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and the protein expressions of MOR, DOR, and KOR in thymus were measured by Western blot. Flow cytometry assay was used to detect the levels of T lymphocyte subtypes in the peripheral blood. RESULTS Surgical trauma induced decreased the mRNA expression level of MOR in both thymus (P<0.01) and L3`-L5 DRGs (P<0.05). Moreover, EA treatment not only significantly attenuated the MOR protein and mRNA expression in the thymus (both P<0.05), but also markedly increased expression of DOR and KOR opioid receptor in thymus (P<0.01). However, the mRNA expressions of opioid receptors were not regulated by EA in the DRG (all P>0.05). Furthermore, T lymphocyte population of CD3+ and CD4+ was decreased in the peripheral blood after surgical trauma (both P<0.01). EA treatment can significantly elevate the population of CD3+ (P<0.01), CD4+ (P<0.05) and CD8+ T cells (P<0.01). Intraperitoneal injection of the non-selective opioid receptor antagonist naloxone blocked the up-regulation of T lymphocytes by EA. CONCLUSION EA may improve postoperative immunosuppression through the peripheral opioid system.

Abstract
PURPOSE The purpose of this study was to demonstrate the feasibility and safety of laparoscopic-assisted anterior resection (LAAR) for colorectal cancer in a local Asian population. METHODS This is a retrospective review of all patients with colorectal cancer operated from November 2017 to October 2018. Main variables of interest were demography, type and surgery, length of stay (LOS), and the involvement of proximal and distal doughnut. Postoperative complications were analysed using chi-square or Fisher exact and Mann-Whitney tests. RESULTS There were 23 patients with a mean age of 62.5 ± 12.2 years. The mean time from diagnosis to surgery was 97.1 ± 154.84 days. There were 12 patients in the LAAR group and 11 in the open anterior resection (OAR) group. Duration of surgery was shorter in OAR (129.58 ± 51.38 minutes) compared to LAAR (147.91 ± 39.37 minutes). Mean LOS was shorter in the LAAR group with 5±1.5 days compared to the OAR group of 7.42 ± 4.25 days. However, there was no significant P-value for both duration of surgery (P = 0.322) or LOS (P = 0.87). A total of 3 complications were recorded after OAR and 2 after LAAR. Both groups had clear proximal and distal margins with 16 (12-18.5) harvested lymph nodes in LAAR and 18 (16-22) in OAR, which were equal (P = 0.155). CONCLUSION This study reports a shorter LOS in the minimally invasive group of 2 days with similar oncologic resection outcomes. This shows that LAAR is feasible in Malaysia and has potential outcome benefits.

Abstract
BACKGROUND The aim of this study was to find the better treatment for colorectal cancer (CRC) by comparing robot-assisted colorectal surgery (RACS), laparoscopic-assisted colorectal surgery (LACS), and open surgery using network meta-analysis. METHODS A literature search updated to August 15, 2017 was performed. All the included literatures were evaluated according to the quality evaluation criteria of bias risk recommended by the Cochrane Collaboration. All data were comprehensively analyzed by ADDIS. Odds ratio (OR), mean difference (MD), and 95% confidence interval (CI) were used to show the effect index of all data. The degree of convergence of the model was evaluated by the Brooks-Gelman-Rubin method with the potential scale reduction factor (PSRF) as the evaluation indicator. RESULTS The PSRF values of operation time, estimated blood loss, length of hospital stay, complication, mortality, and anastomotic leakage ranged from 1.00 to 1.01, and those of wound infection, bleeding, and ileus ranged from 1.00 to 1.02. Open surgery had the shortest operation time compared with LACS and RACS. Furthermore, compared with LACS, the amount of blood loss, complication, mortality, bleeding rate, and ileus rate for RACS were the least, and the length of hospital stay for RACS was the shortest. The anastomotic leakage rate for LACS was the least, but there was no significant difference compared with those of RACS and open surgery. The wound infection rate for LACS was the least, but there was no significant difference compared with that of RACS. CONCLUSION RACS might be a better treatment for patients with CRC.

Abstract
PURPOSE Robotic colorectal surgery continues to rise in popularity, but there remains little evidence on the stress response following the procedure. The aim of this study was to evaluate the inflammatory response to robotic colorectal surgery and compare it with the response generated by open colorectal surgery. METHODS This was a prospective nonrandomized comparative study involving 61 patients with colorectal cancer. The evaluation of inflammatory response to either robotic or open colorectal surgery was expressed as changes in interleukin-1β, interleukin-1 receptor antagonist, interleukin-6, tumor necrosis factor-α, C-reactive protein, and procalcitonin during the first three postoperative days. RESULTS Of the 61 patients, 33 underwent robotic colorectal surgery while 28 had open colorectal surgery. Groups were comparable with respect to age, sex, BMI, cancer stage, and type of resection. The relative increase of interleukin-1 receptor antagonist at 8 h postoperative, compared to baseline, was higher in the open group (P = 0.006). The decrease of interleukin-1 receptor antagonist on postoperative days 1 and 3, compared to the maximum at 8 h, was more pronounced in the open group than in the robotic group (P = 0.008, P = 0.006, respectively), and the relative increase of interleukin-6 at 8 h after incision was higher in the open group (P = 0.007). The relative increase of procalcitonin on postoperative days 1 and 3 was higher in the open group than the robotic group (P < 0.001, P = 0.004, respectively). CONCLUSIONS This study shows that when compared with open colorectal surgery, robotic colorectal surgery results in a less pronounced inflammatory response and more pronounced anti-inflammatory action.

Abstract
BACKGROUND Laparoscopic approaches and standardized recovery protocols have reduced morbidity following colorectal cancer surgery. As the optimal regimen remains inconclusive, a network meta-analysis was undertaken of treatments for the development of postoperative complications and mortality. METHODS MEDLINE, Embase, trial registries and related reviews were searched for randomized trials comparing laparoscopic and open surgery within protocol-driven or conventional perioperative care for colorectal cancer resection, with complications as a defined endpoint. Relative odds ratios (ORs) for postoperative complications and mortality were estimated for aggregated data. RESULTS Forty trials reporting on 11 516 randomized patients were included with the network. Open surgery within conventional perioperative care was the index for comparison. The OR relating to complications was 0·77 (95 per cent c.i. 0·65 to 0·91) for laparoscopic surgery within conventional care, 0·69 (0·48 to 0·99) for open surgery within protocol-driven care, and 0·43 (0·28 to 0·67) for laparoscopic surgery within protocol-driven care. Sensitivity analyses excluding trials of low rectal cancer and those with a high risk of bias did not affect the treatment estimates. Meta-analyses demonstrated that mortality risk was unaffected by perioperative strategy. CONCLUSION Laparoscopic surgery combined with protocol-driven care reduces colorectal cancer surgery complications, but not mortality. The reduction in complications with protocol-driven care is greater for open surgery than for laparoscopic approaches. Registration number: CRD42015017850 (https://www.crd.york.ac.uk/PROSPERO).

Abstract
OBJECTIVE Even though, laparoscopy is not accepted as the current gold standard in colorectal surgery, it can be performed as safely as open surgery. It is also widely accepted that the technique has many advantages. In this study, we evaluated the results of 33 patients with laparoscopic colorectal resection. MATERIAL AND METHODS Thirty-three patients who underwent laparoscopic colon surgery between January 2013 and September 2014 in the General Surgery Clinic at Marmara University Hospital were included in the study. Patients were evaluated in terms of their demographic and tumor histopathologic characteristics, type of surgery and early postoperative complications. RESULTS Laparoscopic colorectal resection was performed for 33 patients who had malignant or benign lesions. The median age was 60 (35-70), and 18 (55%) were male patients. The majority of the patients (90%) were diagnosed with colorectal adenocarcinoma. Half of the patients were T3 and 67% had N0 stage. The median number of retrieved lymph nodes was 17 (4-28). Negative surgical margins were obtained in all patients. The postoperative hospital stay was 5 (4-16) days. Postoperative early complications were observed in only 5 patients. The majority of complications were treated without the need for surgery. No mortality was recorded in this series of patients. CONCLUSION This study showed that laparoscopic colorectal surgery could be performed safely based on its low complication rate, short length of hospital stay, providing sufficient surgical resection and lymph node dissection.

Abstract
INTRODUCTION Changes in immune function after surgery may influence overall outcome, length of hospital stay, susceptibility to infection and perioperative tumour dissemination in cancer patients. Our aim was to elaborate on postoperative differences in the immune status and the intensity of the systemic inflammatory response between two groups of prospectively enrolled patients with colorectal cancer, namely patients undergoing laparoscopically assisted or open colorectal surgery. MATERIAL AND METHODS Blood samples from 77 patients were taken before surgery and then 3 h, 24 h and 4 days after surgery. The inflammatory response was determined by leukocyte counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and procalcitonin levels (PCT). Immune status was determined by phenotypic analysis of lymphocyte populations and the activation of mononuclear cells. CD64 expression and cytokine expression were also determined. RESULTS Patients undergoing laparoscopically assisted surgery had less intraoperative blood loss (p = 0.002), earlier resumption of diet (p = 0.002) and shorter hospital stay (p = 0.02). Numbers of total leukocytes (p = 0.12), CRP (p = 0.002) and PCT (p = 0.23) were remarkably higher 4 days after surgery in patients who underwent an open colorectal procedure. There was an important decrease in monocyte HLA-DR expression 3 h after surgery in patients undergoing laparoscopically assisted surgery (p = 0.03). CONCLUSIONS Our study suggests that minimally invasive surgery provides better short-term clinical outcomes for patients with resectable colorectal cancer. The acute inflammatory response is less pronounced. Post-surgical immunological disturbance in both groups is similar, but we observed a divergent effect of different surgical approaches on the expression of HLA-DR on monocytes. However, our results corroborate the results of previous studies.

Abstract
Background Clinical data indicate that laparoscopic surgery reduces postoperative inflammatory response and benefits patient recovery. Little is known about the mechanisms involved in reduced systemic and local inflammation and the contribution of reduced trauma to the abdominal wall and the parietal peritoneum. Methods Included were 61 patients, who underwent elective colorectal resection without intraabdominal complications; 17 received a completely laparoscopic, 13 a laparoscopically- assisted procedure and 31 open surgery. Local inflammatory response was quantified by measurement of intraperitoneal leukocytes and IL-6 levels during the first 4 days after surgery. Results There was no statistical difference between the groups in systemic inflammatory parameters and intraperitoneal leukocytes. Intraperitoneal interleukin-6 was significantly lower in the laparoscopic group than in the laparoscopically-assisted and open group on postoperative day 1 (26.16 versus 43.25 versus 40.83 ng/ml; p = 0.001). No difference between the groups was recorded on POD 2–4. Intraperitoneal interleukin-6 showed a correlation with duration of hospital stay on POD 1 (0.233, p = 0.036), but not on POD 2–4. Patients who developed a surgical wound infection showed higher levels of intraperitoneal interleukin-6 on postoperative day 2–4 (POD 2: 42.56 versus 30.02 ng/ml, p = 0.03), POD 3: 36.52 versus 23.62 ng/ml, p = 0.06 and POD 4: 34.43 versus 19.99 ng/ml, p = 0.046). Extraabdominal infections had no impact. Conclusion The analysis shows an attenuated intraperitoneal inflammatory response on POD 1 in completely laparoscopically-operated patients, associated with a quicker recovery. This effect cannot be observed in patients, who underwent a laparoscopically-assisted or open procedure. Factors inflicting additional trauma to the abdominal wall and parietal peritoneum promote the intraperitoneal inflammation process.

Abstract
BACKGROUND Postoperative delirium in the elderly is a growing concern. Data regarding significant differences in postoperative cognitive dysfunction (POCD) in elderly persons undergoing laparoscopic versus open colon resection are not well established. OBJECTIVES The goal of this study was to compare the incidence of POCD in laparoscopic versus open colon surgery in an elderly population. DESIGN AND SETTING A prospective nonrandomized pilot study was conducted at an urban tertiary care hospital. PARTICIPANTS The study included patients aged 65 years and above, without documented dementia who underwent elective colon surgery. MEASUREMENTS We collected demographic and clinical data, including age, sex, polypharmacy, and comorbidities. The subjects underwent pre- and postoperative Cambridge Neuropsychological Test Automated Battery (CANTAB) testing. Worsening individual scores from the Paired Associated Learning (PAL) and Spatial Working Memory (SWM) portions of CANTAB determined the presence of POCD. Inflammatory cytokine (i.e., IL-6) levels were measured pre- and postoperatively. RESULTS We enrolled 44 subjects (26 laparoscopic and 18 open surgery). The two groups did not differ significantly in age, sex, polypharmacy, and comorbidities. The average incidence of POCD was 47%. PAL scores worsened in 12/23 (52%) in the laparoscopic group and in 7/15 (47%) in the open group. These group differences lacked statistical significance (p = 0.75). SWM scores worsened in 14/25 (56%) in the laparoscopic group and in 6/18 (33%) in the open group, which was also not statistically significant (p = 0.12). No age difference occurred between the 'worsened scores' group and 'stable scores' group, and older age was not associated with POCD. IL-6 levels were higher in the open versus the laparoscopic group (p < 0.0001). CONCLUSION In this pilot study, the average incidence of POCD was not statistically different between elderly subjects undergoing open versus laparoscopic surgery. Age did not influence the occurrence of POCD. Although inflammatory markers were significantly higher in the open group, consistent with a higher degree of stress response, this group did not have higher rates of delirium. This association is worth to be investigated in a larger sample.

Abstract
The persistent phase of postoperative ileus (POI) is mediated by inflammatory activation of the resident myeloid immune cell population in the gut wall, likely elicited by neurogenic activation. Mast cells are thought to play a critical role in this inflammatory response and involvement of mast cells in POI has been investigated and described thoroughly in experimental studies. Intestinal manipulation (IM) leads to degranulation of mast cells, resulting in an increase in mast cell proteases in peritoneal fluid and gut tissue. The inflammatory infiltrate formed in the intestinal wall thereby impairs gastrointestinal motility. In the clinical study by Berdun et al., the experimentally known association between mast cell degranulation and delayed motility is shown in a clinical setting. These findings are important and open up therapeutic opportunities to reduce or prevent POI. In this mini-review, the role of mast cells in POI is discussed. Furthermore, an update is given on the involvement of the inflammatory response in POI and potential therapeutic strategies.

Abstract
BACKGROUND The development of modern videoendoscopy enables surgeons to perform laparoscopic resection of colonic cancer. AIM This manuscript evaluated the literature concerning clinically relevant differences in the short and long-term course after laparoscopic or conventional resection of colonic cancer. METHODS An investigation of meta-analyses from randomized controlled clinical trials comparing laparoscopic and conventional surgery for colonic cancer was carried out. RESULTS The incidence of intraoperative complications was higher during laparoscopic surgery, the duration of surgery was increased and blood loss was less when compared to open surgery. Overall morbidity and the incidence of surgical complications were decreased after laparoscopic surgery. General morbidity and mortality were not different after laparoscopic or open resection of colonic cancer. Duration of hospital stay was shorter but was also associated with the type of perioperative care (i.e. traditional or enhanced recovery). Following minimally invasive or conventional resection, the incidence of tumor recurrence (local and distant) and the duration of survival (overall and disease-free) showed no differences. Wound implantations were rare after both operative techniques but with a tendency to occur more often after laparoscopic than open resection. CONCLUSION Laparoscopic resection of colonic cancer has clinically relevant short-term benefits for the patients and long-term results are not different from open colectomy. However, most of the patients included in randomized controlled trials underwent right or left colectomy and sigmoid or rectosigmoid resections. Data with a high level of evidence concerning carcinomas of the flexures or the transverse colon do not exist. Suitable patients with colonic cancer should undergo laparoscopic resection by experienced surgeons.

Abstract
BACKGROUND Operative injury to the body from all procedures causes a stereotypical cascade of neuroendocrine, cytokine, myeloid, and acute phase responses. This response has been examined commonly by the use of cortisol, interleukin-6 (IL-6), white cell count, and C-reactive protein (CRP). We aimed to determine which markers of the systemic inflammatory response were useful in determining the magnitude of injury after elective operations. METHODS A systematic review of the literature was performed using surgery, endocrine response, systemic inflammatory response, cortisol, IL-6, white cell count, and CRP. For each analyte the studies were grouped according to whether the operative injury was considered to be minor, moderate, or major and then by the operative procedure. RESULTS A total of 164 studies were included involving 14,362 patients. The IL-6 and CRP responses clearly were associated with the magnitude of operative injury and the invasiveness of the operative procedure. For example, the peak CRP response increased from 52 mg/L with cholecystectomy to 123 mg/L with colorectal cancer resection, 145 mg/L with hip replacement, 163 mg/L after abdominal aortic aneurysm repair, and 189 mg/L after open cardiac surgery. There also appeared to be a difference between minimally invasive/laparoscopic and open procedures such as cholecystectomy (27 vs 80 mg/L), colorectal cancer resection (97 vs 133 mg/L), and aortic aneurysm repair (132 vs 180 mg/L). CONCLUSION Peak IL-6 and CRP concentrations consistently were associated with the magnitude of operative injury and operative procedure. These markers may be useful in the objective assessment of which components of Enhanced Recovery after Surgery are likely to improve patient outcome and to assess the possible impact of operative injury on immune function.

Abstract
OBJECTIVE The efficacy of laparoscopic treatment of rectal cancer remains unclear, and little is known about its effect on sphincter preservation. We compared short-term outcomes of laparoscopically assisted and open surgeries following neoadjuvant chemoradiotherapy (CRT) for mid and low rectal cancer. METHODS This study enrolled 137 patients with mid-low rectal cancer who underwent curative resection, 51 by laparoscopically assisted (Lap group) and 86 by conventional open (Open group) surgeries, following neoadjuvant CRT from July 2007 to July 2012. The clinical and surgical findings of the two groups of patients were prospectively collected and analyzed. RESULTS Three patients (5.9%) in the Lap group were converted to an open procedure. The mean operating times were similar in both groups. The Lap group had a significantly higher rate of sphincter preservation (62.7% versus 41.9%, P = 0.018) and significantly lower mean blood loss than the Open group. Mean times to first flatus, start of a normal diet, and overall postoperative hospitalization were longer for open surgery. The complication rate (11.8% versus 31.4%, P = 0.009) was significantly lower in the Lap group. Mean distal resection margin, involvement of the circumferential resection margin (2.0% versus 3.5%, P = 1.000), and mean lymph nodes harvested (12 versus 11; P = 0.242) were equivalent in the two groups. CONCLUSIONS Laparoscopically assisted surgery following neoadjuvant CRT is safe for patients with rectal cancer and provides favorable short-term benefits but without compromising oncologic outcomes. This sphincter-preserving procedure may be a treatment of choice for patients with lower rectal cancer.

Abstract
INTRODUCTION Racial disparity in the treatment of colorectal cancer (CRC) has been cited as a potential cause for differences in mortality. This study compares the rates of laparoscopy according to race, insurance status, geographic location, and hospital size. METHODS The 2009 Healthcare Cost and Utilization Project: Nationwide Inpatient Sample (HCUP-NIS) database was queried to identify patients with the diagnosis of CRC by the International Classification of Diseases, Ninth Revision (ICD-9) codes. Multivariate logistic regression was performed to look at age, gender, insurance coverage, academic versus nonacademic affiliated institutions, rural versus urban settings, location, and proportional differences in laparoscopic procedures according to race. RESULTS A total of 14,502 patients were identified; 4,691 (32.35 %) underwent laparoscopic colorectal procedures and 9,811 (67.65 %) underwent open procedures. The proportion of laparoscopic procedures did not differ significantly by race: Caucasian 32.4 %, African-American 30.04 %, Hispanic 33.99 %, and Asian-Pacific Islander 35.12 (P = 0.08). Among Caucasian and African-American patients, those covered by private insurers were more likely to undergo laparoscopic procedures compared to other insurance types (P ≤ 0.001). The odds of receiving laparoscopic procedure at teaching hospitals was 1.39 times greater than in nonteaching hospitals (95 % confidence interval [CI] 1.29-1.48) and did not differ across race groups. Patients in urban hospitals demonstrated higher odds of laparoscopic surgery (2.24, 95 % CI 1.96-2.56) than in rural hospitals; this relationship was consistent within races. The odds of undergoing laparoscopic surgeries was lowest in the Midwest region (0.89, 95 % CI 0.81-0.97) but higher in the Southern region (1.14, 95 % CI 1.06-1.22) compared with the other regions. CONCLUSIONS Nearly one-third of all CRC surgeries are laparoscopic. Race does not appear to play a significant role in the selection of a laparoscopic CRC operation. However, there are significant differences in the selection of laparoscopy for CRC patients based on insurance status, geographic location, and hospital type.

Abstract
BACKGROUND Studies have examined whether tumor expression of PTGS2 (also known as COX-2), an enzyme inhibited by nonsteroidal anti-inflammatory drugs such as aspirin, is associated with prognosis in patients with colorectal cancer. However, results to date have been mixed. METHODS Using terms for PTGS2 and colorectal cancer, the Medline, Embase, and Web of Science databases were systematically searched for studies published, in any language, until December 2011. Random effects meta-analyses were used to calculate pooled HRs [95% confidence intervals (CI)] for the association between PTGS2 expression and tumor recurrence, colorectal cancer-specific survival, and overall survival. RESULTS In total, 29 studies, which had prognostic data on 5,648 patients, met the inclusion criteria. PTGS2-positive patients were at an increased risk of tumor recurrence (n = 9 studies; HR, 2.79; 95% CI, 1.76-4.41; P < 0.001) and had poorer colorectal cancer-specific survival (n = 7; HR, 1.36; 95% CI, 1.02-1.82; P = 0.04). However, there was funnel plot asymmetry, possibly due to publication bias, for the association with cancer-specific survival but less so for recurrence. PTGS2 expression was not associated with overall survival [(n = 16; pooled unadjusted HR, 1.30; 95% CI, 0.94-1.79; P = 0.11) and (n = 9; pooled adjusted HR, 1.02; 95% CI, 0.72-1.45; P = 0.91)]. CONCLUSIONS PTGS2 expression was associated with an increased risk of tumor recurrence and poorer colorectal cancer-specific survival but not overall survival among patients with colorectal cancer. However, confounding by tumor characteristics such as tumor stage seems likely. IMPACT There is insufficient evidence to recommend PTGS2 expression as a prognostic marker in patients with colorectal cancer. Furthermore, studies providing adjusted results are required.

Abstract
BACKGROUND Clinical experience suggests that anaesthesia using a combination of acupuncture and drugs can reduce the dosage of anaesthetics required for craniotomy, decreasing both the disturbance in physiological functions during the operation and postoperative complications and improving the rate of recovery. The aim of the present study was to investigate the impact of electroacupuncture (EA) on the dynamic equilibrium of the immune system and immune cell populations during the pericraniotomy period. METHODS A total of 56 patients undergoing craniotomy were randomised into three groups: control (C, n=18), EA (A, n=19) and sham acupuncture (S, n=19) groups. Blood samples were collected before anaesthesia (T0) and 30 min, 2 h and 4 h after induction of anaesthesia (T1, T2 and T3, respectively,) to measure the levels of tumour necrosis factor α (TNFα), interleukin (IL)-8, IL-10, IgM, IgA, IgG and full blood count. RESULTS There was no significant difference between the measurements in groups A and S during craniotomy. The levels of IgM and IgA decreased significantly in group C compared with groups A and S at T2 and T3 time points. The levels of total T cells and suppressor T cells in group C decreased significantly compared with groups A and S at T1 and T2, and the level of natural killer cells in group C decreased significantly compared with groups A and S at T1. No significant differences between groups were found in the levels of TNFα, IgG, IL-10, IL-8, leucocytes, neutrophils, monocytes, Th cells or B cells. CONCLUSIONS EA appears to reduce immunosuppression of both the humoral and cellular components during surgery.

Immunologic response after laparoscopic colon cancer operation within an enhanced recovery program. J Gastrointest Surg 2012; 16:1379-88. [PMID: 22585532 DOI: 10.1007/s11605-012-1880-z] [Citation(s) in RCA: 91] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2011] [Accepted: 03/22/2012] [Indexed: 01/31/2023]
Abstract
OBJECTIVE It has been demonstrated that colon operation combined with fast-track (FT) surgery and laparoscopic technique can shorten the length of hospital stay, accelerate recovery of intestinal function, and reduce the occurrence of post-operative complications. However, there are no reports regarding the combined effects of FT colon operation and laparoscopic technique on humoral inflammatory cellular immunity. METHODS This was a prospective, controlled study. One hundred sixty-three colon cancer patients underwent the traditional protocol and open operation (traditional open group, n=42), the traditional protocol and laparoscopic operation (traditional laparoscopic group, n=40), the FT protocol and open operation (FT open group, n=41), or the FT protocol and laparoscopic operation (FT laparoscopic group, n=40). Blood samples were taken prior to operation as well as on days 1, 3, and 5 after operation. The number of lymphocyte subpopulations was determined by flow cytometry, and serum interleukin-6 and C-reactive protein levels were measured. Post-operative hospital stay, post-operative morbidity, readmission rate, and in-hospital mortality were recorded. RESULTS Compared with open operation, laparoscopic colon operation effectively inhibited the release of post-operative inflammatory factors and yielded good protection via post-operative cell immunity. FT surgery had a better protective role with respect to the post-operative immune system compared with traditional peri-operative care. Inflammatory reactions, based on interleukin-6 and C-reactive protein levels, were less intense following FT laparoscopic operation compared to FT open operation; however, there were no differences in specific immunity (CD3+ and CD4+ counts, and the CD4+/CD8+ ratio) during these two types of surgical procedures. Post-operative hospital stay in patients randomized to the FT laparoscopic group was significantly shorter than in the other three treatment groups (P<0.01). Post-operative complications in patients who underwent FT laparoscopic treatment were less than in the other three treatment groups (P<0.05). There were no significant differences between the four treatment groups regarding readmission rate and in-hospital mortality. CONCLUSIONS The laparoscopic technique and FT surgery rehabilitation program effectively inhibited release of post-operative inflammatory factors with a reduction in peri-operative trauma and stress, which together played a protective role on the post-operative immune system. Combining two treatment measures during colon operation produced better protective effects via the immune system. The beneficial clinical effects support that the better-preserved post-operative immune system may also contribute to the improvement of post-operative results in FT laparoscopic patients.

Abstract
OBJECTIVE We sought to investigate the perioperative inflammatory response and immunological function of patients with portal hypertension-induced splenomegaly who underwent laparoscopic (LS) or open splenectomy (OS). METHODS This prospective study investigated a total of 34 patients with splenomegaly due to portal hypertension who underwent either LS (n = 18) or OS (n = 16) between May 2009 and September 2010. Peripheral venous blood samples were taken from these patients prior to surgery and on postoperative days (POD) 1, 3, and 7. The perioperative clinical outcomes and immunological function results were analyzed and compared within each surgical group. RESULTS The demographics of the two groups did not differ. The patients in the LS group experienced longer operating time, less intraoperative blood loss, earlier resumption of diet, and shorter postoperative hospital stay. Both the open and laparoscopic groups exhibited statistically significant differences in interleukin -6 and C-reactive protein levels, and total lymphocyte, CD4 T, and natural killer cell numbers on POD 1 and 3 compared with pre splenectomy. The immune responses in the LS group were significantly lower than those in the OS group. The LS group exhibited better preserved cellular immune response and faster recovery than the OS group on POD 7. CONCLUSIONS An examination of the inflammatory reaction and cellular immune response after LS and OS demonstrated that there are significant differences in the immune responses observed in the two groups. Further human studies are required to determine the permanent effects of LS on immune function.

Abstract
BACKGROUND The purpose of the study was to evaluate the feasibility and efficacy of laparoscopic palliative resection in patients with incurable stage IV colorectal cancer. METHODS We reviewed 100 patients with incurable stage IV colorectal cancer who underwent palliative resection of the primary tumor between 2002 and 2009 at National Cancer Center Hospital East (NCCHE). Outcomes and postoperative course were compared between patients who underwent open and laparoscopic surgery. RESULTS Of the 100 patients, 22 were treated with a laparoscopic procedure and 78 underwent an open surgical procedure. There was no difference in the preoperative characteristics of the two groups. In the laparoscopic group, the mean operation time was significantly longer (177 vs. 148 min, p = 0.007) and the amount of blood loss was significantly lower (166 vs. 361 ml, p = 0.002). Postoperative complications occurred in 5 patients (22.7 %) after laparoscopic surgery and in 21 patients (26.9 %) after open surgery, with no significant difference between the two groups. Time to flatus, time to start of food intake, and hospital stay were all shorter after laparoscopic surgery (3.0 vs. 3.8 days, p = 0.003; 3.6 vs. 5.0 days, p < 0.001; and 12.0 vs. 15.0 days, p = 0.005; respectively). Significantly more patients in the laparoscopic group had >15 % lymphocytes on postoperative day 7 (p = 0.049). Overall survival rates were 73.7 and 75.5 % at 1 year after laparoscopic surgery and open surgery, respectively (p = 0.344). CONCLUSIONS A laparoscopic procedure should be considered for palliative resection of the primary tumor for incurable stage IV colorectal cancer, because the results of this study indicate that the procedure is safe and effective.

Abstract
BACKGROUND Studies dealing with laparoscopic colectomy for cancer have reached conflicting results in regards to various inflammatory cytokines. Most of them have not examined potential differences with the open procedures at later postoperative days, when the immunologic advantage of laparoscopic surgery would be more demanding to demonstrate (for earlier administration of adjuvant treatment). The aim of this work is to detect differences of proinflammatory cytokines between conventional and laparoscopic colectomy for cancer. PATIENTS AND METHODS 30 patients who underwent laparoscopic colectomy were age, sex, and preoperative stage-matched with 30 patients treated by open surgery. C-reactive protein (CRP), interleukin (IL)-1, -6, and -8, and interferon (IFN)-γ serum levels were measured preoperatively, at 24 h, and at the 7th postoperative day (POD). RESULTS CRP and IL-6 postoperative values (24 h and 7th POD) were significantly higher than baseline for both groups (p = 0.001), but the respective values at the 7th POD were less than at 24 h (p = 0.001). IL-1 and -8 levels did not show any differences between assessment timepoints. A higher IFN-γ measurement was demonstrated at 24 h compared with baseline for the laparoscopic group only (p = 0.03). This difference was not maintained at the 7th POD. IFN-γ levels at 24 h and the 7th POD were significantly less for the open compared with the laparoscopic group of patients (p = 0.001). No correlation was revealed between measured serum values and age, sex, tumor location, or stage. CONCLUSIONS This matched case-control study verifies the already reported lack of differences regarding IL-1. Controversy still exists on likely IL-6 differences. The inadequately studied IL-8 does not seem to play an important role in immunologic differences. The immunologically beneficial IFN-γ, produced by the principal effectors of cell-mediated immunity Th1 cells, seems to have a more active presence following laparoscopic colectomy, potentially contributing to an immunologic "advantage" by counteracting "harmful" cytokines, such as IL-1.

Abstract
OBJECTIVES We evaluated differences in cytokine responses and T-lymphocyte subsets following retroperitoneal laparoscopic and conventional open radical nephrectomies for localized renal cell carcinoma (RCC). METHODS A total of 62 patients with T(1)N(0)M(0) staged RCC were randomized to either retro-laparoscopic (n = 31) or open (n = 31) radical nephrectomy. Plasma levels of interleukin-1β (IL-1β), IL-6, and tumour necrosis factor-alpha (TNF-α) were measured separately by enzyme linked immunosorbent assay (ELISA) preoperatively and on postoperative days 1 and 5. Levels of CD3(+), CD4(+) and CD8(+) as well as the CD4(+):CD8(+) ratio were acquired by flow cytometry at the same time points. RESULTS Levels of IL-1β, IL-6 and TNF-α increased significantly compared to preoperative values in both groups (p < 0.05) on postoperative day 1, and all the parameters in the open group were significantly higher than those in the retro-laparoscopy group (p < 0.05). On postoperative day 1, the levels of CD3(+) and CD4(+) and the CD4(+):CD8(+) ratio decreased markedly compared to preoperative values for both groups (p < 0.05). Elevations of the CD4(+):CD8(+) ratio in the retro-laparoscopy group (p < 0.05) and the CD8(+) level in the open group (p < 0.05) were observed when compared with the other group. On postoperative day 5, the levels of CD3(+) and CD4(+) and the CD4(+):CD8(+) ratio in the retro-laparoscopy group, as well as the level of CD8(+) in the open group, returned to about preoperative levels (p < 0.05). Follow-up ranged from 4 to 14 months postoperatively in all 62 patients with a 100% cancer-specific survival rate in both groups. CONCLUSIONS Retroperitoneal laparoscopic radical nephrectomy is associated with the milder cytokine responses caused by trauma and inflammation and the better preserved distribution of T-lymphocytes.

Abstract
OBJECTIVE To systematically evaluate the immune function in patients with colorectal cancer after laparoscopic surgery (LS) and conventional open surgery (OS). METHODS PUBMED, EMBASE, and the Cochrane library were searched and randomized controlled trials (RCTs) comparing the immunological difference between LS and OS were included. Two authors extracted data and assessed trial quality. RESULTS Eleven studies including 695 patients were analysed. Immune-competent cells demonstrated no significant differences between LS and OS in six trials. Eight trials assessed various perioperative plasma cytokine concentrations with no significant differences in interleukin-6 (IL-6) and C-reactive protein (CRP) levels between LS and OS. However, meta-analysis showed higher T suppressor lymphocytes (CD8+) counts on postoperative days (POD) 1-3 and lower plasma levels of CRP on POD 0-1 in LS group compared with OS group. CONCLUSION Although LS groups displayed higher T suppressor lymphocyte (CD8+) counts on postoperative days (POD) 1-3 and lower plasma levels of CRP on POD 0-1, there is no sufficient evidence to support superior preservation of global immune function with LS compared to OS.

Abstract
There is increased interest in robotic techniques for colon resection, but the role of robotics in colorectal surgery has not yet been defined. The purpose of this study was to compare our recent experience with robotic right colectomy to that with laparoscopic right colectomy. From November 2008 to June 2011, a total of 47 consecutive patients underwent elective, right colectomy: 25 laparoscopic right colectomies (LRC) and 22 robotic right colectomies (RRC). All procedures in this study were performed by a single, board-certified colon and rectal surgeon (H.J.L.). Main outcomes recorded included conversion rate, operative time (OT), estimated blood loss (EBL), length of extraction sites, length of stay (LOS), and complications. Data studied were prospectively recorded in a database and were retrospectively reviewed. Mean OT for LRC was 107 ± 36.7 min (median 98, range 48-207) and for RRC was 189.1 ± 38.1 min (median 185, range 123-288, P < 0.001). Mean total operating room time (TORT) for LRC was 158.6 ± 38.1 min (median 149, range 104-274) and for RRC was 258.3 ± 40.9 (median 251, range 182-372, P < 0.001). The tendency lines for both OT and TORT decreased over time for RRC. EBL for LRC was 70.2 ± 52.9 ml (median 50, range 10-200) and for RRC was 60.8 ± 71.3 ml (median 40, range 10-300, P = 0.037). The mean extraction site length for the laparoscopic group was 5.3 ± 1.3 cm (median 5, range 4-11) and for the robotic group was 4.6 ± 0.7 cm (median 4.5, range 3.5-6, p = 0.008). LOS was similar for both groups, as were complications. No cases were converted to open. No leaks occurred and there was no 30-day mortality. RRC is safe and feasible, with similar outcomes to LRC. Operative times were longer for RRC; however, they compare favorably with times for LRC published in the literature. Extraction site length and EBL were less for RRC. However, further study is necessary to demonstrate the clinical relevance of these findings. We are optimistic that OT and TORT will continue to improve.

Abstract
BACKGROUND There is a sequential, high concentration cytokine response after major abdominal surgery. The magnitude of this response has been directly linked to postoperative metabolic derangement, ileus, adhesions, and oncological outcomes. We aimed to compare the local and systemic cytokine response in laparoscopic and open colonic surgery and relate this to postoperative recovery parameters. METHODS Using a prospectively collected patient database, we compared a Study Group (n = 50) of patients undergoing elective laparoscopic colonic resection with a Control Group (n = 25) of patients undergoing equivalent open colonic surgery within an ERAS program. Patients were matched for age, gender, BMI, ASA, Cr Possum, side of resection, diagnosis, and histologic stage. Plasma and peritoneal fluid concentrations of IL-6, IL-8, IL-10, and TNFα were measured at 20-24 h after surgery. The Surgical Recovery Score was determined pre-operatively and at 3, 7, 30, and 60 d postoperatively. All data were prospectively collected, and a priori definitions were used for discharge parameters, complications, and complication severity. RESULTS Peritoneal fluid IL-6 concentration was lower after laparoscopic surgery. There were no significant differences in the other cytokines measured, or in any postoperative recovery outcomes. Significant correlations were found between cytokine levels and discharge criteria achievement, day stay, postoperative complications, and the Surgical Recovery Score. CONCLUSION With the exception of a lower peritoneal IL-6 level, the systemic and peritoneal cytokine response at 20-24 h is similar after laparoscopic versus open colonic resection within an ERAS program, with corresponding equivalent rates of postoperative recovery.

Abstract
PURPOSE Carbon dioxide (CO(2)) pneumoperitoneum can lead to cardiopulmonary loading and complications. By comparing with conventional CO(2) pneumoperitoneum approach, we introduce a novel Laparo-V lifting system for gasless laparoscopic colorectal surgery. METHODS In a prospective study, patients with colonic lesions underwent either Laparo-V gasless (n = 20) or conventional CO(2) pneumoperitoneum (n = 19) laparoscopic colectomy. Twenty patients who underwent open surgery were enrolled as control. Intra-operative monitoring includes blood pressures, heart rate, O(2) saturation, and end-tidal CO(2) (ET-CO(2)). Serum level of interleukin 6 (IL-6), C-reactive protein (CRP), cortisol, and lymphocyte subpopulations (CD4/CD8) were measured repeatedly. Postoperative recovery was indicated by return of bowel function and postoperative hospital stay. RESULTS Patient characteristics were not different between the three groups. There were three conversions in each laparoscopy group, making conversion rates 15% and 15.7% for Laparo-V and CO(2) pneumoperitoneum groups, respectively. Vital signs remained stable in Laparo-V and open surgery groups; while, elevated ET-CO(2) and heart rate were noted in CO(2) pneumoperitoneum group. Both laparoscopy groups had a significant faster recovery and shorter hospital stay than the open surgery group. Postoperative elevation of IL-6, CRP, and cortisol level was observed in all the three groups, of note, the change was most significant in the open surgery group. CONCLUSIONS Laparo-V gasless laparoscopic approach is feasible in various colorectal procedures. It carries advantages comparable with those of CO(2) pneumoperitoneum; while, the intra-operative hemodynamic was more stable. Therefore, laparoscopic approach using the Laparo-V system could be beneficial to patients with high cardiopulmonary risk and represents an alternative for minimally invasive surgery.

Abstract
Laparoscopic surgery has been associated with many short-term benefits such as a shorter time to recovery, return of bowel function, less pain, and a decrease in wound infection rate. Several animal and human experiments have demonstrated an immunologic and oncologic benefit of minimally invasive surgery. Whether these results will translate into similar results in human settings is unclear. Although the first published prospective randomized clinical trial suggests better long-term outcomes for patients undergoing laparoscopic surgery, results from other ongoing randomized, controlled clinical trials are needed to verify this controversial result.

Abstract
BACKGROUND The local and systemic humoral response after colorectal surgery is thought to affect postoperative recovery. It is commonly claimed that laparoscopic surgery elicits a diminished inflammatory response than equivalent open surgery. Despite these claims, the evidence is conflicting. Therefore, we aimed to systematically review the results from randomized controlled clinical trials comparing the humoral response associated with laparoscopic versus open colorectal surgery. MATERIALS AND METHODS A high-sensitivity search was conducted independently by two of the authors with no language restriction. Studies were identified from the Cochrane Central Register of Controlled Trials (CENTRAL/CCTR), Cochrane Library, Medline (January 1966 to January 2009), PubMed (1950 to January 2009), and Embase (1947 to January 2009). Relevant meeting abstracts and reference lists were manually searched. Data analysis was performed using Review Manager ver. 5.0. RESULTS Thirteen randomized controlled trials were included. Meta-analysis demonstrated a significantly higher serum IL-6 on d 1 after open colorectal resection for neoplasia (n = 97) compared with laparoscopic resection (n = 76, P = 0.0008) without significant heterogeneity. Data for plasma IL-6 were heterogeneous, with no apparent difference between groups. No other significant differences were identified, and there were not enough data on local peritoneal humoral factors to allow meta-analysis. CONCLUSION Open colorectal resection for neoplasia is associated with higher postoperative serum levels of IL-6 on d 1 than equivalent laparoscopic surgery. The aetiology and clinical significance of this finding is uncertain, and further studies are required to elucidate any differences in the local humoral response which may be more clinically relevant in surgery for this indication.

Abstract
PURPOSE Improved survival in patients with stage III colon cancer after a laparoscopic colectomy (LC) has been reported by Lacy et al. (Lancet 359:2224-2229, 6), and preserved immunity was suggested as the reason for the survival advantage. The aim of our study was to clarify the existence of an immunological benefit after laparoscopic colon cancer surgery (LC) compared to open colon surgery (OC). METHODS From January 2006 to November 2007, 74 patients with clinical stage III colon cancer were prospectively assigned to undergo a LC (n = 35) or an OC (n = 39). The immune factors were examined preoperatively, and on the first and fifth days postoperatively (POD1 and POD5). RESULTS The cellular immune factors were significantly decreased; however, there was no significant difference between the LC and OC groups except for the mHLA-DR. The LC group had a better preserved mHLA-DR on POD5 than did the OC group (p = 0.015), in addition to a faster recovery (p < 0.005). CONCLUSION The mHLA-DR on POD5 was affected less by the LC compared to the OC. The LC demonstrated minimal immunological advantage when compared to the OC. However, further study is required to clarify the immunological benefits of the LC on colorectal cancer prognosis.

Abstract
About 90-92% of patients with carcinoma of the colon are treated surgically. For other surgeons, laparoscopic surgery for the treatment of malignancies remains controversial because of concerns about the adequacy of lymphadenectomy, the extent of resection, early findings of port-site metastasis and the lack of data on long-term results. In our experience, there are no differences between the laparoscopic and laparotomic techniques, and only advantages if the laparoscopic technique is use correctly. We essentially agree with the good results of many studies published in the last ten years, but we are extremely confident that it is necessary to have a good learning curve and a high-volume cases hospital to obtain good results through a laparoscopic approach. So laparoscopic colorectal surgery should be performed only by surgeons who have completed training in this approach and who perform the procedure often enough to maintain a good level of competence.

Abstract
PURPOSE Laparoscopic-assisted sigmoidectomy is an attractive but sometimes challenging operative technique for the treatment of diverticulitis of the sigmoid colon. The aim of this study was to compare, with respect to early postoperative analgesic demand and postoperative pain, laparoscopic-assisted sigmoidectomy with a laparoscopic-facilitated technique. In the laparascopic-facilitated technique, the sigmoid colon is removed conventionally via a cosmetically inconspicuous incision after prior laparoscopic mobilization. PATIENTS AND METHODS Patients subjected to elective sigmoidectomy for diverticulitis were randomized to either laparoscopic-assisted or laparoscopic-facilitated sigmoidectomy. All patients had piritramide-based, patient-controlled analgesia. The cumulative postoperative consumption over 96 hours was defined as the primary end point. Postoperative pain, fatigue, pulmonary function, and resumption of bowel function were secondary endpoints. RESULTS : Forty-five patients were randomized according to the protocol to laparoscopic-assisted sigmoidectomy (n = 22) or laparoscopic-facilitated sigmoidectomy (n = 23). The analgesic consumption between the two groups was equivalent (61.3 (9-171) mg piritramide/96 hours vs. 64.3 (18-150) mg piritramide/96 hours; P = 0.827). Patients with laparoscopic-assisted sigmoidectomy had lower pain levels on Day one and Day two. Cumulative pain levels over 96 hours and over the whole 7-day observation period, however, were not significantly different, although postoperative fatigue and pulmonary function were significantly different. Duration of surgery was slightly shorter for laparoscopic-assisted sigmoidectomy (127 (47-200) vs. 135 (60-239) minutes; P = 0.28), but recovery of bowel activity was faster after laparoscopic-facilitated surgery. There was no significant difference in morbidity. CONCLUSION Overall, the postoperative outcome was roughly equivalent after both techniques of laparoscopic sigmoidectomy. Therefore, laparoscopic-facilitated sigmoidectomy could be considered as an alternative to laparoscopic-assisted sigmoidectomy in technically difficult cases of diverticulitis subjected to laparoscopic surgery.

Abstract
Laparoscopic surgery has widely spread in the treatment of colorectal cancer. In Japan, a nation-wide survey has shown that a rate of advanced colorectal cancer has increased gradually and reached 65% of the total cases for colorectal cancer in 2007. For colon cancer, many randomized controlled trials regarding short-term outcome demonstrate that laparoscopic surgery is feasible, safe and has many benefits including reduction in a peri-operative mortality. In terms of long-term outcome, four randomized controlled trials insist that there are no differences in both laparoscopic and open surgeries. However, there are still more important issues including long-term oncological outcome for advanced colon cancer, cost effectiveness and the impact on quality of life of patients. Meanwhile, for rectal cancer, a controversy persists with regard to the appropriateness of laparoscopic surgery because of concerns over the safety of the procedure and a necessity of lateral lymph node dissection for lower rectal cancer. At present, laparoscopic surgery is acceptable for Stage I colon cancer, whereas there are controversies for Stage II/III colon cancer and each staged rectal cancer because of inadequate clinical evidences. Whether laparoscopic surgery further spreads to be applied for colorectal cancer or not, it would be confirmed by Japanese large-scale phase III trial (JCOG0404) estimating oncological outcome for Stage II/III colon cancer and a Phase II trial estimating the feasibility for Stage 0/I rectal cancer in near future.

Abstract
Laparoscopic surgery is widespread in the treatment of colorectal cancer. In Japan, a nationwide survey has shown that the rate of advanced colorectal cancer has increased gradually to 65% of total laparoscopic surgeries in 2007. Many randomized controlled trials have demonstrated that in the short term, laparoscopic surgery is feasible, safe, and has many benefits, including reduction of peri-operative mortality. In terms of long-term outcomes, four randomized controlled trials suggest that there are no differences in laparosupic and open surgery for colon cancer. However, important issues, including long-term oncological outcome, cost effectiveness, and the impact on the quality of life of patients, should be addressed in well-designed large-scale trials. In Japan, a retrospective multicenter study has demonstrated that the short-term outcomes of laparoscopic surgery are beneficial, and the long-term outcomes are the same as for open surgery. In 2004, a prospective large-scale randomized controlled trial (JCOG0404) to compare laparoscopic surgery with open surgery was started to evaluate oncological outcomes for advanced colon cancer. This trial is supported in part by a Grant-in-Aid for Cancer Research from the Japanese Ministry of Health, Labour, and Welfare. In the present study, laparoscopic surgery is found to be acceptable for stage I disease of colon cancer, whereas it is controversial for stage II/III disease because of inadequate clinical evidence. Whether laparoscopic surgery is acceptable for advanced colon cancer or not should be confirmed by the Japanese large-scale prospective randomized controlled trial (JCOG0404) in the near future.

Abstract
UNLABELLED Although laparoscopic surgery for colorectal cancer improves post operative recovery, its use for curative treatment especially for rectal cancer is still controversial. The present study is an attempt to analyze the results of the safety and feasibility of laparoscopic surgery including short-term results for rectal cancer. METHODS This study accumulated 109 patients with rectal cancer retrospectively who underwent laparoscopic surgery. Patients with rectosigmoid colon cancer were excluded from this study. Patients' data, perioperative data including morbidity and mortality, surgical data were analyzed, and the 3-year disease-free survival data were calculated by Kaplan-Meier method, according to the location of the tumor and the UICC stage. RESULTS There were 71 males and 38 females who underwent laparoscopic surgery for rectal cancer. Mean age of them was 63.7+/-12.5 years. The mean BMI was 22.6+/-2.8 kg/m(2). The operative procedure was low anterior resection (LAR) in 80 cases, abdominoperineal resection (APR) in 14 cases, intersphincteric resection (ISR) in 14 cases, and Hartmann's procedure in 1 case. The operation time was 237.0+/-71.6 minutes. Blood loss was 165.0+/-163.8. The postoperative morbidity was 22.9%. The postoperative mortality within 30 days after surgery was not experienced. The 3-year disease-free survival rate was 94.2% after curative surgery. According to the UICC stage, the 3-year disease survival rate was 100% in stage 0/I, 89.1% in stage II, and 84.6% in stage III. CONCLUSIONS Laparoscopic surgery for rectal cancer was safe and feasible including postoperative morbidity, mortality and postoperative short-term results. Further study is necessary to clarify the quality of laparoscopic surgery including the postoperative long-term results.

Abstract
Oncologic safety has now been demonstrated for laparoscopy-assisted surgery for colon adenocarcinoma after 3 and 5 years of follow-up. Pooled data from large multicenter and smaller single-center trials demonstrate that the modality conveys significant short-term benefits as compared with open surgery, although the full potential has probably not yet been reached. Currently, the data supports improvements in wound morbidity, intraoperative blood loss, narcotic analgesia requirements, time to resumption of bowel movements, and time to discharge from hospital. There is a large potential for improved short-term results when combined with current and developing enhanced-recovery programs. For rectal cancer, the role of laparoscopic surgery is less clear. Data from the first large multicenter trial suggest that laparoscopic dissection may compromise the circumferential resection margin, and this issue will be the focus of ongoing and planned trials. Certain short-term benefits have been shown in pooled analyses of smaller nonrandomized trials, such as a decrease in overall morbidity and a marked reduction of duration of postoperative hospital stay.

Abstract
INTRODUCTION It's been demonstrated laparoscopic access determines a lower surgical stress, by measurement of several markers as different interleuquines (IL) or C-reactive protein (CRP). Endothelin 1 (ET-1) is a powerful vasoconstrictor produced in renal endothelium scarcely studied in laparoscopy. The objective of this study is to analyze immune response during laparoscopic and open donor nephrectomy, in a porcine experimental model by means of measuring IL-2, 10, tumoral necrosis factor alpha (TNFalpha), CRP and ET-1. METHODS Twenty pigs underwent left nephrectomy, 10 by laparoscopy and 10 by open approach in an experimental model. Both groups were monitorized IL-2, 10, TNF alpha, ET-1 at basal, immediately post surgery, first, third, fifth and seventh days after procedure. RESULTS The comparative analysis between groups demonstrated a significant increase in levels of CRP (1.44+/-0.88 vs 1.32+/-0.14 mg/dl, p=0.046), TNF alpha (131.14+/-41.37 vs 57.19+/-23.71 pg/ml, p>0.001) and ET-1 (0.91+/-0.49 vs 0.56+/-0.5 fmol/ml, p=0.001) of open nephrectomy group, as a higher levels of IL-2 in laparoscopic group. CONCLUSIONS Open donor nephrectomy determines a higher immune response than laparoscopic approach. The importance of this fact over the ischemia-reperfusion syndrome or the immediate function of graft is not clearly established.

Abstract
Anemia of inflammation in patients with acute or chronic acute-phase activation is a common clinical problem. Hepcidin is a peptide shown to be the principal regulator of the absorption and systemic distribution of iron. Main inducers of hepcidin are iron overload, hypoxia and inflammation, where the latter has been linked to hepcidin via increased interleukin-6 (IL-6). This article addresses the impact and time course of postoperative acute-phase reaction in humans following heart surgery on prohepcidin, hepcidin, hematological markers and IL-6 concentrations. Serum concentrations of prohepcidin, hepcidin, IL-6 and hematological iron parameters were studied in five male patients without infection before and after heart surgery. This study, which is the first to report the impact on serum hepcidin and serum prohepcidin concentrations in patients following surgery, clearly demonstrates the induction of hypoferremia due to the postoperative acute-phase reaction. Significant changes were seen for serum iron concentration, transferrin saturation, total iron binding capacity and hemoglobin concentration. A significant increase in ferritin concentration was seen 96-144 h postoperatively. Additionally, there were significant alterations in both serum hepcidin after 96-144 h and serum prohepcidin after 48 h compared with preoperative values. Serum prohepcidin decreased, whereas serum hepcidin increased. In conclusion, changes in serum prohepcidin were followed by an increase in serum hepcidin. This speaks in favor of a chain of action where proteolytic trimming of serum prohepcidin results in increased serum hepcidin. However, hypoferremia appeared prior to the changes in serum prohepcidin and serum hepcidin.

Abstract
BACKGROUND Although minimally invasive surgery has been accepted for a variety of disorders, laparoscopic resection of colorectal cancer is performed by few. Concern about oncological radicality and long term outcome has limited the adoption of laparoscopic surgery for colorectal cancer. OBJECTIVES To determine long-term outcome after laparoscopically-assisted versus open surgery for non-metastasised colorectal cancer. SEARCH STRATEGY The Cochrane library, EMBASE, Pub med and Cancer Lit were searched for published and unpublished randomised controlled trials. SELECTION CRITERIA Randomised clinical trials comparing laparoscopically-assisted and open surgery for non-metastasised colorectal cancer were included. Studies that did not report any long-term outcomes were excluded. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed the studies and extracted data. RevMan 4.2 was used for statistical analysis. MAIN RESULTS Thirty-three randomised clinical trials (RCT) comparing laparoscopically-assisted versus open surgery for colorectal cancer were identified. Twelve of these trials, involving 3346 patients, reported long-term outcome and were included in the current analysis. No significant differences in the occurrence of incisional hernia, reoperations for incisional hernia or reoperations for adhesions were found between laparoscopically assisted and open surgery (2 RCT, 474 pts, 7.9% vs 10.9%;P = 0.32 and 2 RCT, 474 pts, 4.0% vs 2.8%; P = 0.42 and 1 RCT, 391 pts, 1.1% vs 2.5%;P = 0.30, respectively). Rates of recurrence at the site of the primary tumor were similar (colon cancer: 4 RCT, 938 pts, 5.2% vs 5.6%; OR (fixed) 0.84 (95% CI 0.47 to 1.52)(P = 0.57); rectal cancer: 4 RCT, 714 pts, 7.2% vs 7.7%; OR (fixed) 0.81 (95% CI 0.45 to 1.43) (P = 0.46). No differences in the occurrence of port-site/wound recurrences were observed (P=0.16). Similar cancer-related mortality was found after laparoscopic surgery compared to open surgery ( colon cancer: 5 RCT, 1575 pts, 14.6% vs 16.4%; OR (fixed) 0.80 (95% CI 0.61 to 1.06) (P=0.15); rectal cancer: 3 RCT, 578 pts, 9.2% vs 10.0%; OR (fixed) 0.66 (95% CI 0.37 to 1.19) (P=0.16). Four studies were included in the meta-analyses on hazard ratios for tumour recurrence in laparoscopic colorectal cancer surgery. No significant difference in recurrence rate was observed between laparoscopic and open surgery (hazard ratio for tumour recurrence in the laparoscopic group 0.92; 95% CI 0.76-1.13). No significant difference in tumour recurrence between laparoscopic and open surgery for colon cancer was observed (hazard ratio for tumour recurrence in the laparoscopic group 0.86; 95% CI 0.70-1.08). AUTHORS' CONCLUSIONS Laparoscopic resection of carcinoma of the colon is associated with a long term outcome no different from that of open colectomy. Further studies are required to determine whether the incidence of incisional hernias and adhesions is affected by method of approach. Laparoscopic surgery for cancer of the upper rectum is feasible, but more randomised trials need to be conducted to assess long term outcome.

Abstract
OBJECTIVE To determine the clinical effectiveness of laparoscopic and laparoscopically assisted surgery in comparison with open surgery for the treatment of colorectal cancer. BACKGROUND Open resection is the standard method for surgical removal of primary colorectal tumours. However, there is significant morbidity associated with this procedure. Laparoscopic resection (LR) is technically more difficult but may overcome problems associated with open resections (OR). METHODS Systematic review and meta-analysis of short- and long-term data from randomised controlled trials (RCTs) comparing LS with OR. RESULTS Highly sensitive searches of nine databases identified 19 primary RCTs describing data from over 4,500 participants. Length of hospital stay is shorter, blood loss and pain are less, and return to usual activities is likely to be faster after LR than after OR, but duration of operation is longer. Lymph node retrieval, completeness of resection and quality of life do not appear to differ. No statistically significant differences were observed in rates of anastomotic leakage, abdominal wound breakdown, incisional hernia, wound and urinary tract infections, operative and 30-day mortality, and recurrences, nor in overall and disease-free survival up to three years. CONCLUSIONS LR is associated with a quicker recovery in terms of return to usual activities and length of hospital stay with no evidence of a difference in complications or long-term outcomes in comparison to OR, up to three years postoperatively.
